Bhutan is possibly one of the best examples of sustainable eco-tourism and one country that is committed to this concept inspired by the Buddhist views of the interdependence between man and nature. The national policy of high value, low volume tourism asks every visitor to be sensitive to social, nature and environment systems that is trying to preserve the best of its traditions in a rapid changing world. The government is determined to safeguard its heritage to ensure that the people maintain their dignity against the onslaught of globalization and modernization.

Visitors may experience Bhutan only on all-inclusive package tours for which a fixed daily tariff is set by the Royal Government of Bhutan. This tariff covers the following services: accommodation & all meals, transport, guide, entrances fees to museums, monuments and cultural sites, and additionally a cultural program for visitors traveling in a group of three or above.

Tourism has been strictly limited in Bhutan so that traditional culture can be preserved and nurtured. The Bhutanese are highly religious people and therefore it is important to show respect and understanding for local customs and way of life, especially while visiting places of religious significance. The tourism industry in Bhutan is founded on the principle of sustainability, meaning that tourism must be environmentally and ecologically friendly, socially and culturally acceptable, and also economically viable. For these reasons, tourism is carefully monitored and the number of tourists visiting Bhutan is kept to an environmentally manageable level.
